Title: Container for storage of semiconductor
Inventor: KOBAYASHI KEIJI
IPC: H01L23/08
Filed: 1978-01-18
Abstract: PURPOSE: To increase the reliability for the container of the semiconductor by laminating the reinforced ceramics via the adhesive of the silver solder or the like.  
     CONSTITUTION: The semiconductor container is formed by adhering via the silver solder or the like the reinforced ceramics which features less occurrence of minute cracks caused by the thermal impact produced at the junction time or the uneven stress caused by attachment of the electrode. This results in the increment of both physical and chemical strength as well as the reliability and safety. The reinforced ceramics is obtained by giving the chemical etching via the boiling phosphoric acid to the substrate of alumina, glass and the like. And the ceramics thus obtained is further reinforced through the thermal etching or the sudden heating-up and cooling-down.

Title: Caulking pin for damper disc
Inventor: IDOTA OSAMU
IPC: F16D13/64
Filed: 1985-01-14
Abstract: PURPOSE:To make it possible to obtain a sufficient fixing strength, by forming the cross-sectioned shapes of both center and small diameter sections of a pin in non-circular shapes, and by ensuring a sufficient area for the seat surface section of the pin. CONSTITUTION:A stud pin 28 has its center section 56 which is in an oval cross-sectioned shape elongated substantially in the circumferential direction of a disc. Further, small diameter sections 57 formed at both ends of the stud pin 28 have a substantially circular shape concentric with the center B. Thus, since the stud pin 28 has its center section 56 elongated in the circumferential direction of the disc, the seating sections between the center section 56 and the small diameter sections 57 may have a large area. Accordingly, it is possible to enhance the fixing strength of the stud pin 28 to a subplate 26.

Title: Recording and reproducing circuit and magnetic disk device using the circuit
Inventor: KORENARI TAKAHIRO
IPC: G11B20/10
Filed: 1998-01-13
Abstract: PROBLEM TO BE SOLVED: To suppress the baseline fluctuations of reproduced waveforms in the magnetic disk device in which a magnetoresistive element is used. SOLUTION: It has been thought that baseline fluctuations are related to the distance between a magnetic recording medium and a reproducing element and the fluctuations of the distance are related to the temperature fluctuations of a magnetoresistive effect element. Therefore, the cycle of the distance fluctuations corresponds to the cycle of the baseline fluctuation. For example, in a contact recording system, the cycle of the baseline fluctuations is controlled by controlling the cycle of the unevenness of the surface of a magnetic recording medium and the frequency of the fluctuations (a fluctuation frequency) is determined from the relative speed between the medium and a reproducing head and the cycle of the fluctuations.  On the other hand, the cutoff frequency of a high pass filter is set as high as possible within the range in which no distortion occurs in the reproduced waveforms. Then, by controlling the fluctuation frequency to be lower than the cutoff frequency of the high pass filter, the baseline fluctuations (shown in the ordinate of the attached diagram) are completely suppressed.
